This symbol represents the constructor function for integers, specifying
the base. It takes two arguments, the first is a positive integer to denote
the base to which the number is represented, the second argument is a string
which contains an optional sign and the digits of the integer, using 0-9a-z
(as a consequence of this no radix greater than 35 is supported). Base 16 and
base 10 are already covered in the encodings of integers.

This symbol represents the constructor function for rational numbers. It
takes two arguments, the first is an integer p to denote the numerator and the
second a nonzero integer q to denote the denominator of the rational p/q.

A symbol to convey the notion of the gamma constant as defined in
Abramowitz and Stegun, Handbook of Mathematical Functions, section 6.1.3. It
is the limit of 1 + 12 + 13 + ... + 1/m - ln m as m tends to infinity, this
is approximately 0.5772 15664.
